Abstract

The invention discloses an anus expanding device used for expanding the anus and the anal tube. The anus expanding device brings convenience to a doctor for examination or operation and comprises a chassis, a guide rail disc, an expanding rod and a connecting ring. The guide rail disc rotates on the chassis. One end of the expanding rod slides in a guide rail groove. The guide rail groove is designed in an eccentric mode or involute mode, and the other end of the expanding rod is driven to move. The connecting ring is a fixed compression part which can prevent the guide rail disc and the expanding rod from being disengaged. The anus expanding device has the advantages that the anus and the anal tube can be gradually and controllably enlarged in parallel, the anal sphincter can gradually adapt to the enlarging range of the anus expanding device, the anal fissure phenomenon can be avoided, and pains of patients are relieved.
